I 7 J0 .11 66 Z Jmmw WZ'Zwm ATTORNEYS UNITED STATES PATENT MATTHEW WILSON, or GARRISON, 'IfowA.

To all whom 'it may concern." I

Be it known that I, MATTHEW WILSON, a citizen of the United States, residing at Garrison, in the county of Benton and State of Iowa, have invented a new and useful Traction-Wheel, of which the following is'a specification.

This invention relates to traction wheels such as are provided with-Jmud-hook attachments. The object of the invention is to provide a traction wheel having adjustable mudhooks and improved operating mechamsm for the mud-hooks carried entirely by the traction wheel'and having no connection whatever with the body of the traction enin any suitable manner,

ficmg any of its advantages.

.and construction.

gine or other vehicle.

Withthe foregoing and other objects in view,- which will appear proceeds, he inventlon resides in the combination and arrangement of parts and in the details of construction hereinafter described and. laimed, it being understood that changes in the recise embodiment of invention herein. disc osed can be made within the scope of the followinclaims without departing from the spirit 0- the invention or sacri- In the accompanying drawings forming part of this specification; .Figure 1 is a sectional view, partly in elevation, of a traction wheel'equipped. with the improvements of the present invention. Fig. 2 is a view similar to Fig. 1 but. taken at a right angle therea to. Fi 3 is a perspective view showing one-hal of the slidahle sleeve.

Like reference numerals indicate corresponding parts in the different figures of the rawings.

The traction wheel in, connection with which the improvements of the present invention are used, can be of any suitable form One convenient form of traction wheel has been illustrated in the drawing as consisting of an outer rim or periphery 1, the hub 2 mounted on the axle 3 and held in position by the nut or other suitable device 4 and the spaced sets of spokes 5 and 6. The traction wheel can he provided on its periphery, if desired, with a plurality of fixed mud-hooks 7.

- In carrying out the present invention, the rim 1 of the wheel is provided with a plurality of ad'ustable mud-hooks 10. While the mud-hoo s 10 may be adjustably mounted said hooks preferspecification of Letters Patent. Application filed June 18. 1906.. Serial No. 322.294. 1

asthe description ably are pivotally connect device 12 which extends" throughetlieirimtl2 and is provided with a nut L'3,'r,tlie:ibolt.-l'2i serving as means for pivot-'allynconnectin the mud-hook with the rim ofthe'wheelf The preferred mechanism, which is carried entirely by the traction wheeh fonoperating the adjustable mud-hook's]1-0, consists? of a shaft 20 which is suitablyhjounnaledi upon:

the wheel by means of thearms 2lfiwhidharo- 3-1 .1

connected with the spokes" ori otheri'suitable portions of the wheel. The sh'af 20iis bent. to form a pair of approxirnately shaped crank portions 22, the meeting end's hf are connected with a handlef'or controlling 5: lever 23. The V-shapedicrank 'ortions'*%22 are each provided with a suitabe anti-fries tlon roller 21, which rollers arefadapted t o bear against the outer end=25 ofa slev'e' ed at5fone=end,2as mdicated at 11, with a bolt-orothr suitable:-

which is mounted for longitudinal, sliding f movement upon the hub 2 While the sleeve 26 may be oiany suitable formwandcone struction, said sleeve preferably is formed'i'n two halves which are suitably vbolte'di toether. The outer end 2 5 of the sleeve ilfi' is F 2 orined with a central *openingLi27mtor1fit around the nut 4. The sleeve 26 .isuformed with a plurality of longitudinally extending spoke slots 28 through WhichLeXtend.the

outer set of spokes 5, as shown clearlydnthe drawing. Surrounding tl-ie hub 2 is a coil spring 29 which bears at itsinner end against t e spokes .6, and at its outenendagainst the sleeve 26 ,thus constituting automatic means for moving the sleeve 26. outwardly. The

sleeve 26 1s provided around its periphery with a plurality of ears or lugs 35 with which are connected links 36 the outer ends of which are pivotally connected at 37 with arms 38 secured to or formed integral with the adjustable mud-hooks 10 and projecting be desired to extend the adjustable mudhooks, so that they will take a-deeper grip-in the ground, the controlling lever 23 is grasped, while the traction engine 18 standing still, and drawn outward to the position shown 111 Flg. 2, so that it is approximately parallel with the axle 3. When the controlling lever 23 is operated, the anti-friction rollers 24 move across the outer face or end 25 of the sleeve 26, thus forcing said sleeve inward upon the hub 2 against the tension of the coil spring-29, as shown clearly in Fig. '52,.

whereby the/links 36 cause the inner ends of the mud-hooks 10 to be moved outward as shown in Fig. 2, so as to take a firmer grip in the ground or surface over which the traction wheel is moving. i

In'order to provide means for locking the controlling lever 23 in the position shown in 1 Fig.2, I mount upon the outer end 25' of-the sleeve 26 apair of approximately semi-cylin drlcal socket pleces 40 having beveled ends 4]. up which the anti-friction rollers 24 will move until they snap into the socket portions 40 andare thus held in position by the action of the coil spring 29 which forces the sleeve 26 outward.

From the foregoing description it will be. apparent that-the operating mechanism for the adjustablemud-hooks '10 is carried en-" ti'rely by the traction wheel, whereby the necessity of providing operating mechanism earned by the traction engine and connected intermediately'with the traction wheel, is

avoided.

" The improved device 'of this invention is strong, simple, durable and inexpensiveln.
